To all whom il! may concern: t

Be it known that we, Aus'rin lt, Mannen and-FRANK Hftoonnrir, citizens ol the United States, residing at Tyrone and Allegheny, respectively, in th counties 5 ol' Blair and Allegheny, respectively, and State of Pennsylvania, have invented. certain new and useful Improvements in Sinokeonsuzners, oi `which the following' is a speci ation.

ln manufacturing localities and particularly where l cheap l'uel, such as'sol't coal is used in 'industrial pursuits, the question of disposing, or getting rid ol' the smoke, presents a serious problem. Many and various have been the attempts to solve the problem on an economical and practicable basis but so lar as has been l ascertained, the dilliculty has not been successfully overcome.

This invention has for its object to eliminate the free carbon held in suspension in the products of combustion emanating from furnaces and other smoke producing devices and which iree carbon is the source of evil in the smoke question.

In accordance with this invention, the free carbon with which the hot air and gases is laden is precipitated, steam being one oi the essentials .in the success- Aful operation, since it combines with the iree carbon and causes thesame to precipitate with the particles ol condensation resulting from cooling of4 the steam in its travel through a passage, or conductor, in the length of which condensers are located", as well as mixing devices for combining the steam and smoke.

An embodiment of the invention and a practical a plication thereof is shown in the accompanying drawings, in which:

Figure l is a side view ot a. passage, or conductor, provided with adj unctive means for effecting the desired result. Fig. 2 is a top plan view of a portion oi the conductor showing the parts on a larger scale. Fig. 3 is a vertical, central longitudinal section of the receiving portion oi the conductor illustrating the parts on a. larger scale. lfigj 4 is a view similar to Fig. 3 of the delivery, or rear portion of the conductor. Fig. 5 is a vertical transversesection oi a condense on' the line x-5u oi Fig. I3. I

Corresponding and like parts are referred to in the following description and indicated in all. the views of the drawings by the same reference characters.

The conductor l may be ol any igtnistriiction, size and length and may be elevated, arranged at the surlace,`o r located below the surface to any depth as iound best adapted to location and conditions.

A stack 2 is in coinn'iunication with the delivery end of the conductor .to discharge the hot air and gases at a. convenient point alter the smoke, or free carbon llas been eliminated therefrom.

i An air inlet 3 is provided at the receiving end oi the l conductor and is usually closed but may be opened more or less to admit air in regulable quantity.

A steam pipe 4 likewise is in connection With the receiving end ol' the conductor and connects with the exhaust oi engines, boilers, or other contrivances giving oit spent steam, thereby preventing discharge o the steam into the atmosphere which is likewise-objectionable since it hangs as a pall over the locality,I ebstructs sunlight and is otherwise injurious and objectionable. f

The nuineral indicates the discharge from the smoke producer and in the case ol a battery or gang of furnaces, each furnace has an independent connection with the conductor by means oi a pipe-duct or conveyer 5. .7()

It is to be understood in this connection that comlniunication between the furnace,v or smoke producer,

- and the conductor l may be had in any manner so long l l i as the smoke and products ot' combustion are delivered tothe conductor in which the separation takes placer. A dellector (S is arranged within the conductor opposite to the discharge of each smoke eonveyer 5 to prevent interference of oney discharge with the other as also to give an initial upward direction to the smoke and products oi combustion when entering the conductor. The nozzle, or discharge ol the steam pipe 4 is likewise deflected in the saine direction as the delectors 6 and has a like purpose. Y

Mixers 7 are located at intervals in the length oi the conductor and each consists of a fan so arranged as to physically combine the particles loi steam with the particles oi carbon contained inthe smoke, gases and products of combustion.

The mixer, er lan 7, rnay-be of any construction, in the event of the fan being mounted se as toy rotate in aplane corresponding with the length oi the conductor as indicated most clearly in Figs. 3 and 4.

A wall, or baille 8 is projected across the space of the conductor so as to Cover one-hall, preferably the Alower hall', ot the ian, thereby causing the curreit 95 through the conductor to act-upon the upper halt of the ian only and effect rotation thereoi with the eurre'nt. The mixers, or lans 7, are automatically oper ated by the drait' or current through the conductor and are not positively driven by direct connection with any source of motive power. I

A number oi condcnsers are located in the length of the conductor, cach condenser consisting of a chainber, or coniparn'lent 9 ol suitable dimensions of larger capacity than the conductor. A wall 10 projects up- I105 ward. from the bottom of the chamber and terminates within a short distance from the top thereof.

The wall 10 constitutes a baille and the current of moist smoke impacted thereagainst, is relieved in. a great 'mensili-c ol' the excessive humidity, the saine be- 110 smclting or reverberatory iurnaccs, or in any adaptais precipitated in the bottom oi the chamber.

` 'from an engine, or blown off from a boiler. or other genarranged in the compartment 16 and covers the lower fa common point of discharge by proper inclination oi ing condensed, or precipitated, the particles of conv densation carrying with them the free carbon which ingress is had into the condenser through a suitable door 11 and communication may be had from one part of the condenser -to the otherthrough an opening 12 provided in the wall, or partition l0. y

To assist the separation of the free carbon, a jet of steam is injected into the condenser across the path of the current through the conductor. This jet is delivered through a nozzle, or pipe 13, which preferably inclines to the direction of the conductor so as to throw a jet across the current at an`upward and forward angle. The jet of steam supplied through the nozzle, or pipe 13 may be derived from any source and is preferably waste, or spent steam, such as exhausted yGratorl y Y At, or near, the delivery end oi the conductor, is locaied a fan 14, the purpose of which is to create a positive current through the conductor. -This fan blower may be oi any type commonly employed for creating an air blast. The fan blower 14 is positively v driven from a suitable source oi power, a drive belt 15 being shown as power translating means. The Conv ductor is enlarged to form a compartment 16 in which the fan blower 14:` is located.A As illustrated, the fan blower is similar in construction and arrangement to the mixing fans 7 and in order that no back current may-be created in the conductor a wall, or. balrie 17, is

half of the fanit being understood that the ian is rotated so that its upper'portion travels towards the stack 2 so as to create "a4 suction, or current, through the conductor fromfthe receiving end 3 tolthe discharge 2.y n

In order that accessmay be readily had to the interior of the conductor, manholes 18 are provided at suitable points in the length thereof.

1t is observed, that the steam commingling with the smoke discharged into the conducton'renders said E smoke moist or humid and the elimination of the excessive humidity-by condensation results in separation and precipitation of the free carbon which constitutes the objectionable feature oi smoke.

The precipitation and condensation takes place throughout the length of the conductor and more rap idly in the condensers, and the liquid precipitate com mingling in the bottom ofthe conductor is directed to the bottom of the conductor.

As shown,4 a drain opening 19 is provided in the bot-` tom oi the last condenser and the bottoin oi the con ductor slopes from opposite ends towards said opening, the walls, or partitions 8 and 10 having openings 20 in their lower ends so as not lo obstruct the passage of the liquid precipitatein iis travel towards the discharge, or drain opening 19.

The invention is-equally applicable to steam boiler furnaces, either singly, or in battery, as well as to tion to a Smoke producpftdevice employedl in the industrial arts.' l I.

When'thecondurztor cougtructcd under ground, it may be'iorm'ed oi`mnsoury, but when at the surface,

steam. Obviously if the spent or waste steam has suijcient force, it may be :discharged into the condensers through thenozzles 13. The steam combining with the smoke so as to eliminate the free particles oi carbon therefrom may be supplied to the conductor at any point or points in the length thereof.

While the primary purpose of the fan 14 is to create ,i positive current through the conductor, it may also serve to augment the draft throughthe furnaces discharging into said conductor, thereby materially prometing the combustion of the fuel as Well as intensiiying the heat With the result that from a given quantity of fuel a greater number oi units of heat are evolved and utilized..

Having thus described the invention, what is claimed as new is:
